The extraradical hyphae of arbuscular mycorrhizal fungi (AMF) harbour and interact with a microbial community performing multiple functions. However, how the AMF-microbiome interaction influences phosphorus (P) acquisition efficiency pathway is unclear. Here we investigated whether AMF their hyphal microbiome play role in promoting organic mineralizing under field conditions. We developed an in-growth core system for using PVC tubes sealed membrane different size pores (30 or 0.45 μm) to...

Abstract In August 2022, an exceptionally long-lasting heat wave (HW) affected the middle and lower reaches of Yangtze River basin. This study uses JRA55 daily reanalysis datasets to elucidate thermodynamic characteristics evolution historical extreme HWs in this region via budget equation. are generally characterized by occurrence anticyclonic circulation anomaly throughout troposphere positive air temperature with maximum amplitude boundary layer. The can induce compression heating entire...

Dinoflagellate cyst and pollen records from marine sediments off the southwestern African coast reveal three major aridification periods since last glaciation an environmental correlation between land sea. Abundant of desert, semi-desert, temperate plants 21,000–17,500 cal yr B.P. show arid cold conditions in Africa that correspond to low sea surface temperatures enhanced upwelling shown by dinoflagellate cysts. Occurrence Restionaceae record suggests northward movement winter-rain regime...

This study used a [13C]DNA stable isotope probing (SIP) technique to elucidate direct pathway for the translocation of 13C-labeled photoassimilate from maize plants extraradical mycelium-associated phosphate-solubilizing bacteria (PSB) that mediate mineralization and turnover soil organic phosphorus (P) in hyphosphere. Inoculation with PSB alone did not provide any benefit but utilized added phytate-P their own advantage, while inoculation Rhizophagus irregularis significantly promoted shoot...

A sensitive and specific competitive electrochemical immunosensor for the detection of Hg (II) using a modified electrode based on molybdenum disulfide/reduced graphene oxide/gold (MoS2/rGO/Au) nanocomposites was developed in this study. The were characterized assembled with an antibody against immunosensor, demonstrating good electrical activity, high affinity specificity. Free solution can be measured by reaction element sample antigen fixed electrode. differential pulse voltammetry (DPV)...

Abstract A pre‐existing anticyclonic anomaly over Scandinavia/western Russia played a crucial role in the persistent low temperature event southern China January 2008. This extended eastward along arctic coast of Eurasian continent, and then induced China. Considering that anomalies rarely to central Siberia, simultaneous presence this feature with vigorous Rossby wave propagation African‐Asian jet stream is found be fundamental factor occurrence event.

To extract and identify the metabolites of strain A217 as well its antifungal spectrum control effect on various plant pathogens. Strain was identified a Streptomyces sp. which most similar to lienomycini. An antimicrobial test indicated that inhibited several pathogenic fungi strong antibacterial such Phytophthora capsici, Botrytis cinerea, Sclerotinia sclerotiorum, Fusarium oxysporum, Pseudomonas syringae Xanthomonas campestris. in vivo tissue demonstrated fermentation broth exerted...

Seesaw relationship in intensity between the surface Aleutian and Icelandic Lows (AIS) is a manifestation of atmospheric teleconnection that bridges interannual variability over Pacific Atlantic particular winter months. Analysis 20th Century Reanalysis data reveals strength timing AIS have undergone multi-decadal modulations conjunction with those structure Arctic Oscillation (AO) signature, extracted leading mode sea-level pressure (SLP) extratropical Northern Hemisphere. Specifically,...

The mycorrhizal status of plants in the Chenopodiaceae is not well studied with a few controversial reports. This study examined arbuscular (AM) colonization and growth response Ceratocarpus arenarius field greenhouse inoculation trial. rate AM fungi C. in-growth cores was low (around 15%). Vesicles intraradical hyphae were present during all stages, but no arbuscules observed. Sequencing analysis large ribosomal rDNA subunit detected four culturable Glomus species, G. intraradices, mosseae,...

Gallium is a metal that literally melts in your hand. It has low toxicity, near-zero vapor pressure, and viscosity similar to water. Despite possessing surface tension larger than any other liquid (near room temperature), gallium can form nonspherical ...Read More

Based on the Japanese 55-year reanalysis daily data, this study finds that frequency of persistent cold events from Lake Balkhash to Baikal exhibits a clear interdecadal variation. Circulation characteristics, such as variations in regional event frequencies, are focus study. During 57-year period, subperiod mid-1980s late 1990s inactive characteristics compared with those before and after during period. On subseasonal timescale, typical circulation patterns characterized by wave-train...

ABSTRACT Based on the daily Japanese 55-year Reanalysis (JRA-55) dataset, this study reveals that southern Europe/western Asia (SEWA) and northern China are two large-scale regions have exhibited consistent interdecadal variations in frequency of persistent hot events (PHEs). Over past 58 summers, period approximately from 1973 to 1996 represents an inactive for occurrence PHEs over regions, whereas antecedent subsequent periods active periods. At subseasonal time scale, regional SEWA...

To investigate land–sea interactions during deglaciation, we compared proxies for continental (pollen percentages and accumulation rates) marine conditions (dinoflagellate cyst alkenone-derived sea surface temperatures). The were from published data an AMS-radiocarbon-dated sedimentary record of core GeoB 1023-5 encompassing the past 21,000 years. site is located at ca. 2000 m water depth just north Walvis Ridge in vicinity Cunene River mouth. We infer that parallelism between increasing...

The daily fields from three reanalysis datasets are utilized to explore the subseasonal influence of teleconnection patterns on surface air temperature (SAT) over southern China. Due similarity results different datasets, ensemble mean is then used in this study. After applying false discovery rate significance test, composite reveal that positive Western Pacific (WP) events, East Atlantic (EA) Scandinavian (SCA) and Eastern Atlantic/Western Russia (EAWR) events have an SAT anomalies timing...

Abstract Based on the Japanese 55-year reanalysis dataset, this study identifies 92 Europe–Siberia blocking high events (ESBs) over 60 winters (November–March) from 1958/59 to 2017/18. According influence surface air temperature at 2 m middle and lower reaches of Yangtze River, ESBs are classified into three types: cold, neutral, warm. Although cold-type dominant, number warm-type is not negligible. The present mainly focuses differences between ESBs. Both characterized by height anomalies...

Based on Japanese 55-year daily reanalysis data, the present study reveals that a strong Siberian high (SH) is preceded by three teleconnection patterns—namely, Scandinavian (SCA) pattern, western Pacific (WP) and Polar/Eurasian (POL) pattern. Accordingly, SH events are classified into types. Composite results show there evident differences among types in their typical circulation characteristics impacts surface air temperature (SAT) East Asia. The SCA type characterized wave-train anomaly...
